For Immediate Release

Firmware Update: V3.0 for F4

We are pleased to announce the F4 v3.0 Firmware update.  For existing users of the F4, this update will add some key functionality found in the new F8n.


  • Advanced Look-Ahead Hybrid Limiters

Advanced Look-Ahead Hybrid Limiters add a 1 millisecond delay that enables the limiters to “look ahead”, anticipating clipping before it’s recorded. Limiting can be applied to each of the 6 channels simultaneously at full resolution, with 10 dB of headroom and controls for setting threshold, attack, and release.


  • Zoom AutoMix™ function

Zoom AutoMix™ takes some work off your plate, automatically adjusting the levels of your mix and helping you reduce any ambient sound. Now with this smart software, you can focus on what really matters – capturing a well-balanced mix.


  • Improved TC accuracy when powered off
  • Digital Boost for headphone monitor (up to +24dB)
  • Ability to record to SD card and USB Audio Interface simultaneously
